There are 10 S/T slots, so there can be a maximum of 10 continuous spell cards active, 5 on each side of the field. The Field Spell card is a special kind of continuous card, so technically that makes 11 in total if you count it.
Any amount, so long as you have the spell/trap zone spaces for them.
I would recommend 20 Spell and Trap Cards, and 20 monster cards, or if not, you can have any amount of Spell Cards, as long as there are 40 or under, because 40 cards are the number of an official deck
You can place as many on the field as you wish. That is to say, if you somehow had 10 Spell Cards in hand, you are allowed to activate them all - you'd activate one, let it resolve, and it would go to the graveyard after. Keep in mind though you have only 5 regular S/T slots, and a Field Spell Card slot. If you activate any continuous Spells, or Set a spell, then these are taking a slot up. If you fill all your slots like this, you cannot activate any other cards until a slot is freed up.
There are approximately 180 players that have Active LPGA playing cards.
60 it said on a box
You are only allowed 11 cards as a maximum on a field, you have five monster card slots, five spell/trap slots, and a Field Spell Card slot.
my estimated guess would be around, possibly 600 or more
Raviel: You must tribute 3 of your fiend type monsters to summon him, you may tribute a monster to increase his attack by the attack of the tributed monster until the end of the turn. Hamon: You must tribute 3 of your face up continuous spell cards to summon him, if he is in defense mode you opponent can not attack your other monsters, if you destroy your opponent card by attacking with him you inflict 1000 damage to your opponent. Uria: You must tribute 3 of your face up continuous trap cards to summon him, he gains 1000 attack(he has 0 by deafault) for every continuous trap card in your gaveyard, in addition once each turn you can destroy one of your opponets set spell or trap cards.

Under normal circumstances, you can Normal Summon one monster, set 5 S/T cards, and place a field spell card too. But this is in no way a hard limit, because you can special summon, you can activate spell cards and place more. Normally you'll run out of cards in hand because you won't be able to replace them, but nonetheless, there's no rule stating a limit to how many special summons or Spell cards you can activate in a main phase, only Normal Summons.
There are 11 Arcana Force monsters and three Arcana Force Spell/ Trap cards giving a grand total of 14 Arcana Force cards.
There is no hard limit. You can perform one Normal Summon or Set, as many special summons, and activate as many spell or trap cards as you can, keeping in mind the zone restrictions. Apart from that, there is no actual limit, and one deck abused that to the max. The "Tunde's Trunado" deck spent 11 minutes on its first turn. It would play continuous spells to add counters to Royal Magical Library, draw cards from that, bounce the continuous spells back to hand with Giant Trunade, play them again for more card draw, recycle Giant Trunade over and over by various means. Then it would win in the oppoenent's draw step with Life Equalizer and Blasting the Ruins.
